SSS-rank mental-type Hunter Kang Hanul!

After being caught in a mana storm, he is transported to the Demon Realm.

After spending an immeasurable amount of time there, he subjugates the Seven Demon Kings and becomes a Demon God.

Then, he finally returns to Earth.

His only family, his older brother, is dead, leaving behind only his nephew.

But his nephew is now the youngest-ever Minister of the Dungeon Management Department?!

And the country has turned into a complete mess, overrun with traitors while neighboring nations treat it like a pushover.

They dare look down on his nephew?

Uncle Kang Hanul is going to start by smashing an embassy.
